小编给大家分享一下怎么利用pygame实现打飞机小游戏,相信大部分人都还不怎么了解,因此分享这篇文章给大家参考一下,希望大家阅读完这篇文章后大有收获,下面让我们一起去了解一下吧!
最近上实训课,写了这么一个简单的小玩意。运行效果如下:(这个是有音效的,不过这个展示不了因为这里只能上传GIF)
由于我使用的是笔记本所以对于屏幕来说是进行了缩放的,例如,我的笔记本缩放了125%
但是问题在于我们的pygame和其他的一些库例如selenium其实是按照100%显示的像素来算的。所以这个时候我们需要进行一个换算。
这个也好算: 当前显示像素比 = 100%显示像素比 X 缩放比
我们只需要换算一下就好了。这里我定义了一个类,来实现我们的需求,自动检测我们的电脑的屏幕缩放比,之后换算。
from win32 import win32api, win32gui, win32print from win32.lib import win32con from win32.win32api import GetSystemMetrics class ChangeRealSize(object): ''' 该类主要对屏幕进行像素适配,按照缩放比对像素进行换算为100%显示 示例: RealSize = ChangeRealSize() x=RealSize.getreal_xy(500) 此时就可以换算为当前屏幕的像素 ''' def get_real_resolution(self): """获取真实的分辨率""" hDC = win32gui.GetDC(0) w = win32print.GetDeviceCaps(hDC, win32con.DESKTOPHORZRES) h = win32print.GetDeviceCaps(hDC, win32con.DESKTOPVERTRES) return w, h def get_screen_size(self): """获取缩放后的分辨率""" w = GetSystemMetrics (0) h = GetSystemMetrics (1) return w, h def getreal_xy(self,x): '''返回按照100%来算的真实的像素值''' real_resolution = self.get_real_resolution() screen_size = self.get_screen_size() screen_scale_rate = round(real_resolution[0] / screen_size[0], 2) try: x = x/screen_scale_rate except: #对笔记本进行适配,一般而言在100%比的机器上x不会出错 x=1.25 return int(x)
屏幕绘制直接使用pygame.display.set_mode()的bitl()绘制方法,进行绘制。当然这里的背景是会动的。所以使用到了一个精灵的派生类。
import pygame,random from ChangeRealSize import ChangeRealSize GetReal = ChangeRealSize() class GameSprite(pygame.sprite.Sprite): def __init__(self,image_path,speed=1): super().__init__() self.image = pygame.image.load(image_path) self.rect = self.image.get_rect() self.speed = speed def update(self): self.rect.y+=self.speed class Background(GameSprite): def __init__(self, image_path="./Plane_Img/background1.png",flag=False): super().__init__(image_path) if flag: self.rect.y = -self.rect.height def update(self): self.rect.y+=1 if self.rect.y >= self.rect.height: self.rect.y = -self.rect.height
实现的具体方法如下:
飞机类的实现
这个我是自己定义的所以的话,没有办法直接使用那个自带的碰撞检测,我还定义了一个碰撞检测方法。
这个和游戏类的事件检测配合。
具体思路是用pygame.event.get()进行事件检测。之后检测到按下某一个按键,例如向前移动是,就会设置向前移动的信号,那么这个时候飞机就会一直往前走。当松开后,那么设置信号为假,那么飞机就会停下来。由于飞机会一直在循环里面检测有没有按下那个向前,所以当你长按往前时,飞机会一直往前,直到你松开。
这个子弹和敌机都是精灵派生类的子类。所以的话就一起说一下。
重点要说的时子弹类的碰撞检测,和敌机的碰撞检测。这里主要说一下子弹类,因为这个和敌机类似。只是有些细节不一样。
class Bullet(GameSprite): def __init__(self,P_rect,is_hero=False,bullet_image = "./Plane_Img/bullet-3.gif",hero_rect=None): self.hero_rect = hero_rect self.bullet_image = bullet_image self.speed = 4 self.is_hero = is_hero self.P_rect = P_rect self.screen_height = GetReal.getreal_xy(800) self.screen_width = GetReal.getreal_xy(500) self.actarct_plan = False self.actract_hero=[] super().__init__(self.bullet_image,self.speed) self.rect.x = self.P_rect.x+((self.P_rect.width-self.rect.width)/2) self.rect.y = self.P_rect.y def enemy_bullet(self): #可以在这里计算飞机被击中了多少次 #被击中减少5点 if not self.is_hero: bullet_x = self.rect.x + int(self.rect.width / 2) bullet_y = self.rect.y + int(self.rect.height / 2) hero_plane_x = self.hero_rect.x + int(self.hero_rect.width / 2) hero_plane_y = self.hero_rect.y + int(self.hero_rect.height / 2) subtract_y = abs(int(bullet_y - hero_plane_y)) subtract_x = abs(int(bullet_x - hero_plane_x)) if subtract_y <= int((self.rect.height + self.hero_rect.height) / 2) and \ subtract_x <= int((self.rect.width + self.hero_rect.height) / 2): self.actract_hero.append(1) return True def update(self): if self.enemy_bullet(): #直接在这里计算数字一次减少5 global HERO_PLANE_HP HERO_PLANE_HP-=5 # print(HERO_PLANE_HP) self.kill() if self.is_hero: self.rect.y-=self.speed else: super().update() if self.rect.bottom >=self.screen_height-3 : self.kill()
子弹的话分两种,一个是飞机子弹,一个是敌机子弹,敌机的自带检测碰撞。一方面是方便分数统计(敌机击中飞机几次)了另一方面也是因为飞机是自定义的没有办法用pygame的事件检测(自带的)
这个其实又和飞机的爆炸类似。
主要是检测有没有撞到飞机,之后通过切换图片就好了。当然这个时候我是开了线程的。不然会很快闪过去,换了和没换一样你看不到效果。
切换图片的函数,切换完毕,删除这个敌机类减少内存消耗
这个其实就是一个自己的后面
具体作用就是修改自己的飞机的HP值为99万
当然这个小游戏还没有做完,无敌也有点无聊,玩久了的话。
